HARNESS.

SPECIFICATION forming part of Letters Patent No. 374,430, dated December6, 1887.

Application filed April 2'7, 188?. Serial No. 236,337. No model.)

To (ZZZ whom it may concern.-

nection of the draft-chain between the horses,

thereby dispensing with the use of ordinary traces, rendering thecontrol of plows much easier, and obviating injury to shrubberyand treesby outside traces and projecting singletrees, providing a harness whichis as well adapted for use in connection with wagons, sleighs,stone-boats, and drags, as well as other vehicles, implements, &e.; andmy present invention is an improvement upon the harness for whichLetters Patent were granted to me December 16,1884, No. 309,317; and itconsists in certain features of construction, hereinafter described andclaimed.

Referring to the drawings, Figure 1 is a perspective view of a yokeconstructed in ac cordance with my invention. Fig. 2 is a top View ofthe same. Fig. 3 is a transverse vertical section through one end of theyoke and through one of the segmental bands or singletrees and theelevis uniting them. Fig. 4 is a vertical section through the middle ofthe yoke, its draw-plate, and handle.

This device consists of the yoke proper, A, the central part of which isarched upwardly at a, so that when used in connection with thedraft-pole of wagons, cultivators, reapers, and other implements itpasses over the same, and the ends a conform to the curvature of thesingletrees B.

Upon the middle or top of the arch a of the yoke is secured adraw-plate, D, of novel construction. It has on one side a single eye,d, placed upon the transverse aXis of said plate to receive one end ofthe draft-chain when the horses used are of equal size and strength,andon the opposite side the draw-plate has two eyes, (i placed side byside, and either one of said eyes is adapted to receive the draftchain,so that if either horse is of unequal size or strength of the other theweaker can be given some advantage by shifting the draftchain to the eyefarthest from said horse without danger of the chain shifting out of itsset position, as it occasionally happens with clevises having simplydepressions on its inner surface. As either side of the yoke can be thefront one relatively to the horses, both ends being alike, thedraft-chain can be connected either with the central eye, d, or witheither one of the side eyes. The draw-plate is secured to the yoke bymeans of a bolt, 0, passing centrally therethrough, and to prevent saidplate from turning upon said bolt it has flanges d to bear against theedge of the yoke. Upon the bolt is also placed the handle e and the nute", that securely unites these parts.

To permit the singletrees B to swing sufficiently upon their pivotwithout unduly enlarging the clevis uniting them to the ends of theyoke, the clevises F are used. They are made right and left (in pairs)and are secured to the singletrees so that their doubled-over middleportion, f, is bent or deflected outwardly or toward the outer end ofeach singletree of a pair. To cause the clevises F to revolve oroscillate with the singletrees, they have one edge flanged or bent downat f against the edge of said singletrees. To facilitate the rotation ofthe singletrees upon the ends of the yoke,a washer, g,is placed betweenthem and a bolt, h, unites them, a nut, h be ing screwed upon said bolt.To connect the singletrees with the supporting baekstrap and with theshort traces, an eye, K, is formed in each end of said singletrees bycutting the metal of said singletrees and separating it therefrom onthree sides of said eye, but leaving the bottom portion uncut andbending it out= wardly at that point to form a tongue, is, of su tficient size and strength for the trace-links to engage with, and thetongue has a perforation, k, to receive a pin or a split key in front ofthe links.

Having now fully described my invention, I claim- 1.
